如何使用jQuery获取父元素值? [英] How to get the parent element value using jquery?

问题描述

我有一张表，该表有几行，每行有两个单元格，每个单元格都有几个信息，例如办公室名称，地址和电话号码等.使用jquery分别从每个单元格中提取地址，然后馈入google map geocoder对象以获取点并将其绘制在地图中.现在，在每次命中一个Address值时，我还想从jquery正在从中获取地址值的当前单元格中获取电话和办公室名称的唯一值.我需要这些值，以便可以在InfoWindow的InfoWindow中显示这些值.地图?我如何获得这些价值?

I have a table with a couple of rows with two cells in each row and each cell has couple of info like office name, address and phone number etc. Using jquery for each, the address is being pulled out from each cell and fed into google map geocoder object to get the point and plot it in the map. Now at each hit of an Address value, I would also like to grab the unique value of phone and office name from the current cell from which jquery is getting address value..I need those values so i can display those values in the InfoWindow of the map? How do I get those values?

推荐答案

根据this的当前上下文，这应该可以工作:

Depending on the current context of this, then this should work:

$(this).parent().find('.officeName').html();
